It might sound like science fiction, but in a few short years the family dinner table could be laden with steak from a printer and other proteins produced from air, methane or volcanic microbes.
With the explosive success of vegan beef and burger substitutes developed by Beyond Meat Inc and Impossible Foods Inc, the alternative protein sector just keeps growing.
Alternative meat sales could reach US$140 billion — or 10 percent of the global meat industry — within a decade, or a 10-fold increase from current levels, Barclays PLC said.
A new generation of products in the works melds cutting-edge technology with age-old fermentation processes to turn otherwise harmful or everyday elements into essential food ingredients, with the aim of reducing agriculture’s massive carbon footprint.
Agriculture, forestry and other land use activities accounted for 23 percent of total net greenhouse gas emissions of human origin from 2007 to 2016, soaring to 37 percent when pre and post-production activity were factored in, UN data showed.
Meanwhile, livestock are responsible for about 14.5 percent of global greenhouse gas emissions, the UN Food and Agriculture Organization said.
Enter Solar Foods Ltd, a Finnish company working on an edible protein powder called Solein, which uses water, air and renewable electricity as a way to separate food production from agriculture.
“You avoid land use impacts like clearing forests for agriculture, use of pesticides and use of fertilizers that release greenhouse gases and so on,” Solar Foods cofounder and CEO Pasi Vainikka said.
Solein is made by putting microbes into a liquid and feeding them small bubbles of hydrogen and carbon dioxide, a process similar to making beer or wine, apart from the lack of grapes or grains, he said.
As the liquid thickens, it is dried into a very fine powder that is about 65 percent protein and tastes much like wheat flour.
In September, Solar Foods struck an agreement with Nordic food company Fazer Group to develop products using Solein, which can be used in existing plant-based offerings or future products such as lab-grown meat.
Solein is to cost about 5 euro (US$5.51) per kilogram to produce and would hit the market by 2021, Vainikka said.
“There’s a lot of climate anxiety,” Vainikka said. “And people are looking for hope and solutions, and they’re happy to see companies like ours, so that’s encouraging.”
Another company tackling agriculture’s emissions through fermentation, Bengaluru, India-based String Bio Pvt Ltd, is working to convert methane, a greenhouse gas more potent than carbon dioxide as it traps 28 times more heat, from waste and natural sources into protein powder — initially for animals.
“We said this is probably the best impact we humans can have in this world, where we take something that we don’t need for the environment and convert it into something we do need,” said Vinod Kumar, who founded the company with his wife, Ezhil Subbian.
Such environmental considerations, along with concerns over animal welfare and human health, have driven both demand and supply of alternative proteins, investment firm Unovis Partners managing partner Dan Altschuler Malek said.
He said that just 10 years ago retailers saw alternative proteins as a risky bet, but “today they realize there is a huge demand for all these products.”
Unovis manages New Crop Capital, a fund that invests exclusively in start-ups developing meat, seafood and dairy replacements, including Beyond Meat.
New Crop has also invested in NovaMeat, a Spanish company that uses a special 3D printer to produce steak that can mimic the taste and texture of meat.
The printers produce 3D vegan steaks using cartridge-style syringes that extrude plant-based proteins.
Some have criticized plant-based alternatives flooding store shelves as highly processed and high in sodium, and Harvard University scientists have questioned their role in a healthy diet.
Others, such as the Center for Consumer Freedom, which is backed by the food and beverage industry, have launched campaigns decrying so-called “fake meat” as loaded with chemicals.
Proponents counter that burgers have always been laden with fat and sodium and were never exactly considered health food.
The new generation of proteins is also less processed, said Thomas Jonas, CEO of Sustainable Bioproducts Inc, whose protein is based on microbes found in volcanic hot springs at the US’ Yellowstone National Park.
In that barren, otherworldly and dangerous landscape, researchers “discovered a bunch of life-forms that across millennia evolved to survive in this environment,” he said.
Having raised US$33 million in February, the company plans to produce “a hamburger equivalent” next year through a “novel fermentation” of the microbes.
At full capacity, its 3,250m2 plant in Chicago could produce burgers equivalent to those made from cows grazing on 6,100 hectares of land, Jonas said.
For investors like Altschuler Malek, alternative proteins are all about options for consumers, with three essential caveats.
“It needs to taste great, it needs to meet certain price points and it needs to be able to be manufactured in large volume,” Malek said.
“There are amazing chefs all over the world that are doing plant-based products, but if you cannot convert that into mass manufacturing, it’s really hard to see how that can actually make a change in the world,” he said.
It is also an opportunity for a radical shift in agriculture, which, despite incremental improvements, has remained much the same for centuries, Jonas said.
“Fundamentally, we are surviving on this planet based on an agricultural system that has barely changed in the past 11,000 years ... when we domesticated a handful of plants and animals,” Jonas said.
“New technologies are really giving us tools for a second domestication — things that we didn’t even know were there,” he added.
SIZE MATTERS: Medium-sized hotels that do not have the support of parent groups are more vulnerable and are forced to take action, a REPro Knight Frank researcher said About 50 hotels across Taiwan are seeking to exit the market as they succumb to the bleak business outlook amid international travel restrictions imposed to combat the COVID-19 pandemic. Yomi Hotel (優美飯店) on Minsheng E Road, Sec 1, in Taipei is seeking to transfer ownership with an asking price of NT$950 million (US$32.15 million) and a pledge for a lease contract that guarantees a 3 percent return. The budget hotel, with room rates that start from NT$1,400 per night, maintains normal operations, but has been struggling since March, when the government placed restrictions on inbound and outbound travel. Occupancy rates for hotels in
With the US dollar expected to weaken in the next 12 months due to near-zero interest rates, investors should consider purchasing US corporate bonds, Standard Chartered Bank Taiwan Ltd (渣打台灣銀行) said on Thursday. The bank said that the US Federal Reserve since last month has been buying bonds issued by US companies to curb default rates. The US dollar is forecast to be weaker against the pound, the euro and the yen, as well as the Canadian dollar, the Swedish krona and the Swiss franc, as the greenback lacks high investment returns after the Fed in March slashed the benchmark interest rate
A Bollywood actor’s face tattooed on his arm, Sandeep Bacche’s devotion shocks few in India where stars enjoy semi-divine status, but even there the hallowed silver screen might be losing its shine to streaming services and pandemic fears. “Whenever things get better and theaters begin operations, I will watch three movies a day for sure just as a way to celebrate,” said the Mumbai rickshaw driver, who is recovering from the virus himself. However, others might not join the party. With cinemas shut for months due to a COVID-19 lockdown, and little prospect they will reopen soon, frustrated Bollywood producers have turned to
Polytronics Technology Corp (聚鼎科技) yesterday announced that it is buying Henkel AG’s thermal clad dielectric material (TCLAD) business division for US$26 million as the Taiwanese firm aims to improve its technology, product portfolio and revenue performance. Polytronics, headquartered in the Hsinchu Science Park (新竹科學園區), is a supplier of protection components and heat dissipation materials. The firm entered the metallic heat-dissipation substrate market in 2007 and developed a unique solventless production process. Its board of directors approved signing an agreement with Henkel to acquire the German chemical firm’s TCLAD division in the US. The purchase includes all assets and business interests, including equipment,
